Abstract
The present invention is directed to an attrition resistant carrier product such as silica. Further, this invention is directed to the use of a binder to improve the attrition resistance or reduce the friability of a carrier product such as silica. In an embodiment, the median particle size is from 125 to 300 microns. Selection of the binder is such that the presence and/or addition of the binder does not result in substantial modification of the physical properties of the silica. Suitable binders include Group I and Group II silicates, Group I and Group II aluminates, and mixtures thereof, as identified by the Period Table of Elements.
